In an experiment to investigate the mechanism of the condensation reaction between acrolein and 1, 3-butadiene, the initial rate was measured spectrophotometrically for various different partial pressures of the reactants. The table below shows the initial rates of reaction, v_0, for various partial pressures of acrolein, P, at a temperature of 560 K with 1, 3-butadiene being in excess. Determine the order of the reaction with respect to acrolein. A) 0 B) 2 C) 3 D) 0.5...
